Similarly, the data path comprises a high level interface, a data stack and a low level interface. The high level interfaces communicates with the communication control stack and the low lever interfaces communicate with the hardware access driver, which is closely coupled to the hardware in the MPI. The hardware access driver is interrupt-driven based on the hardware interrupt requests generated by the MPI.
The control stack is used to format and store control and status data. The format of the control and status data is in accordance with the particular protocol being implemented by the external protocol stack.

Similarly, the data stack is used to format and store communications data. The format of the communications data is in accordance with the particular protocol being implemented by the external protocol stack. A personal computing device 1, such as a laptop computer or a personal digital assistant PDA is in data communications with a server 9. The server 9 is typically coupled with a computer network 8, such as the Internet. In this example the typical cellular network is represented by a base station 5 that is coupled with a public switched Compaq Presario 725US Notebook Conexant HSFi Modem network 7, through a mobile switching center 6.
Typically, the base station 5 comprises a radio transceiver used for communicating with the radio transceiver built into the cell phone 3. This forms the wireless link 4 of the communication channel.

The wireless link 4 may comprise a digital or analog signals depending on the specific implementation of the present invention. In the example embodiments described below, digital cellular phone systems are used. The use of a digital cellular phone system in the examples below should not be construed to limit the scope and breadth of the present invention. The base station 5 is typically coupled with the mobile switching center 6 via standard wired telecommunication transmission links. Similarly, wired transmission links are used to connect to the public switched network 7 and to the computer network 8.
Compaq Presario 725US Notebook Conexant HSFi Modem wired link between the public switched network 7 and the Internet 8 is generally referred to as a point-of-presence with respect to the Internet 8. In this example, the end-to-end communication path is completed at the server 9. The server 9 is also connected to the Internet 8 in some fashion. The configuration shown in FIG. Thus, for example, the laptop computer 1 can communicate in this fashion with any server coupled to the Internet 8.
The cellular phone interface component 15 is used to provide electrical connections to the signals on the cellular telephone Compaq Presario 725US Notebook Conexant HSFi Modem. The configuration of the cell phone interface is in accordance with the particular cellular phone 3 used to connect to the present invention. The DTB 14 performs synchronous and asynchronous functions as necessary for the cell phone's data channel and control channel respectively. The USB serial interface engine 13 performs serialization and de-serialization of USB transmissions as well implementing necessary communications and set-up procedures in accordance with the standard USB protocols.
